Take a look at what Rosslyn looked like in 1962 (top photo). You can see the River Place Apartments near the top right which are basically the only structures still prominent on the Rosslyn skyline to this day.
By 1967, the old rail tracks had been removed, the new yet to be named Roosevelt bridge was built and Rt 66 was ready to bring the rising commuter population into the district from VA (second photo).

hey there i am from the d.c. area but am moving soon just found your blog and i will keep it in my bookmarks
From the looks of it, architecture is one of your main interests – do you know of any examples of green architecture around the D.C. metro area?
Green Architecture is going to be THE defining characteristic of architecture and development in the United States over the next ten years. This will clearly be a big element featured at DC Metrocentric. We will try to have some posts next week!
Wow..Looking at both photos, it’s a huge contrast to what the area is today.
I-66 took another 20 years to open. I assume that it just was that stub for most of that time. The road didn’t open until the mid 1980s. You did get a feel for how f-ed up they made Rosslyn though. It was pretty flat with a fairly normal street grid. You don’t feel that anymore.
